on. i? of the cerbureter pro- .til the usual manifold (not shown}. semioutlet is controlled by a Well lmown .4 surrouncis spray nozzle andprovicles in passage. The lower enc'l EZl of said sleeve is of conieslform. to increase the air on, the interior of said sleet e st thatpoint. The said sleeve controls the supply of air to the spray nozzleand is vet-ti celly movable, subject to elevation by the suction clue tothe air passing the spray nozzle. The operation is such that the volumeof air is proportional to the demands of the engine. The movement ofsaid sleeve 20 is controlled by gravity, or preferably by a spring 22which encircles the upper part thereof. The said spring an sleeve areinclosecl by an outer sleeve or cylinder to be again referred to. Itsnormal position is shown in 1 and 5. In order to re dues the supplyoiair and to thus procluce it mixture of greet-er rie llhiiSS -when suchleeeoiries desirable, for example, insure a ready starting of theengine'the sleeve 29 may be lowered to reriuoe the volume oil? airsupply. See Fig. 3. The ssicl sleeve :20 is vertically movable,independently of or with the outer cylinder 23 wfoielz supports it.Thesaiel outer cylinder 23 is provided with. a lower contracted 52% uponwhich the sleeve 20 rests and with on upper flange 25 "which forms aguide for the up yer end of said sleeveQO. The said cylinder 28 isvertically movable in the annular Wall 11 and is hel. in an upperposition by s springQZ. The upper position ofssitl cylinder 23 con trolsthe normal position of sleeve 2G is ecliusteri by a screw 28 "whichengages per flange 25 of said cylinder. the screvv 28 is mounted in aboss 29 extending from the upper portion 17 of the seeing and isproviriei. with s locking spring See Fi 5. 1
